I am uploading the file using the script from "UPLOADIFY" site, The image is uploading successfully, But Now I want to preview the image on my UI Page, I have written some script (Converted image into Base 64 Encrypted code) to preview the image.
Both the functionalities are working fine individually, But I am unable to execute both functionalities one by one. Here is the code I have used Please help Me.
$(document).ready(function() {
$('#file_upload').uploadify({
'uploader' : '/js/uploadify/uploadify.swf',
'script' : 'index.php',
'fileExt' : '*.jpeg;*.gif;*.png',
'fileDesc' : 'Image Files',
'buttonText' : 'Select File',
'sizeLimit' : 102400,
'onSelect' : function() {preview(this);}
});
});
I'm assuming you would like to preview the image onSelect... That is not possible due to security measures in modern browsers which prevent local (user-local) images from being displayed. This means that in order to preview the image you must first upload it (for example, set the upload mode to 'auto' and then onComplete add the temporary image to a div) and then the user would have a button of some sort to 'confirm' that the temporary image is indeed the desired one. That button would then move the temporary image to a definitive folder and add it to the database.
Sorry for not adding code, but I think you can easily manage to do it on your own. There are some great tutorials around too.
Cheers

I am trying to build plug in the image extension (#tiptap/extension-image) to my tiptap editor, however the issue I find is with bigger images, there is no easy way to add a sort of placeholder image or text to tell the user the image is being uploaded.
The current flow is this:
const imageUrl = await doUpload();
editor.chain().focus().setImage({ src: imageUrl }).run()
So between uploading the image and setting the image, there is a delay and no feedback to the user.
So I have tried to extend the Image extension and I am able to create a method to set some text, but then I am not sure how to clear that text. Does anyone have a good solution for this?
I am trying to reset a filepond field to a default image on user action (ie: clicking on a button).
The file could be local or uploaded somewhere (as AWS) it does not matter.
I currently load a default image when the webpage (and therefore the filepond instance / element) is first loaded, so I guess manually calling the load method would do the trick but I can't manage to do that.
I also try with the file-poster plugin, but there is no way to reset the image after it has been deleted.
If you have found a way of doing this or are thinking about something, please let me know :)
Actually #Rik was right, just use addFile function with the option type: "local".
I am loading image from a URL and it's works as expected.
Scenario when the URL no longer valid, i.e if the image was deleted and I do see the default image displays since I created EncodedImage from the Label icon.
I would like to know if there is anyway I can check if the image has actually loaded from the URL?
What I want to achieve is set a different image to a background if the URL image is not found.
Please advise.
Thank you.
The closest thing is to check if the URLImage's isAnimation() method returns true. If it returns true, then the actual image hasn't been loaded yet. If it returns false, it means that the image is already loaded.
Which system do you use to download the image ? Is the image stocked in the Storage, in the FileSystem ?
If you have dowloaded the image using the ConnectionRequest, you may override it's handleErrorResponseCode method and do something when you have the network error code corresponding to no image ( i.e. 204 : no content).
There are many workarounds for this problem. I use this jQuery one
I'm a senior majoring in Computer Science. I'm new at web development. I'm using ASP.NET C# with MS SQL Server. I've been trying to figure out how to load images from the database onto the webpage. I have successfully done this with the following code.
<asp:Image ID="imageClient" runat="server" style="width:100px; height:100px;"/>
protected void LoadImage()
{
ModelDataContext mdc = new ModelDataContext();
byte[] image = (from c in mdc.Clients select c.Logo).FirstOrDefault().ToArray();
string base64String = Convert.ToBase64String(image, 0, image.Length);
imageClient.ImageUrl = "data:image/jpg;base64," + base64String;
}
Right now I'm just doing it for 1 image. I will eventually be using a repeater to display multiple images on the same page.
The problem is with the loading of the image. It does some weird stuff to the masterpage that it uses. It's as if it isn't applying the CSS to the masterpage. But a few seconds later it looks as it should. The problem is definitely with the loading of the image because there is no other loading problems on any of the other pages.
I tried posting pictures of what I am seeing, but my reputation is too low.
The problem isn't browser specific, it does the same thing in all the major browsers...
If anybody could help me with the problem that would be great.

Edit: I realized the images that I was trying to view may have had a filesize too large and it was taking too long to get it from the database and to load the image. My new approach is to save the image to a folder within my project and saving the imageurl in the database to refer to the actual location of the image.
Is this the best approach keeping in mind I am nowhere near at being advanced in Web Dev?
Thanks
Caching the image to a folder can give you benefits such as reducing load on the database. If the web pages are in a busy environment (ie. many users) caching everything you can reducing the load on the database is desirable.
As to the initial image-tag. As far as I remember, the asp:Image doesn't support a Style tag as with html img tag. I think you would need to define a css in a style-sheet (or embedded in the page) and refer to that with the CssClass tag instead - or - use the .Style("property") = "mysetting" in code instead.
F.ex:
imageClient.Style("Width") = "100px"
imageClient.Style("Height") = "100px"
I'm making a website in drupal 7 and need some help.
I created a content type called Itenary where user will upload information and five images.
The images I have taken as Image1, Image2.... Image5 as fields of type image pf the itenary content type.
Now I wish to show these images as something like this
So I go to the views module -> add new view
Now when I had tried this before, I had selected
Show content of type itenary
And it didn't work as I hoped.
So this time, I chose
Show File of type Image
I hope this is the right option for my need.
Then I went to create a block, gave it a name.
Now my dilema is how do I bring those fields of Image1 Image2 .. Image5 into this block ?
The fields it shows by default are related to files and not the field of my content type.
Make sure you have the following steps checked.
1- Try to download jQuery cycle plugin.
2- Create a folder a new folder sites/all/libraries/jquery.cycle and place jquery.cycle.all.js file inside it.
3- Go and test the results :).
Hope this works... Muhammad.
