I am uploading images from my desktop to my list and putting them on gallery. But it doesnt work. pls heeeelp I tried so many solutions already and still not working. :

How are you storing them on the list?  If you are using the Image column type that won't work.  The SharePoint connector doesn't support that column type. To display an image as part of a list you either need to save the Base64 encoded string to a text field or store the image in a library and add a link to the list.

@Pstork1 yeah i am using image column, what should I search or learn to get the base64?

@CNT, I watched it and tried it the link base64.de is not working so I search for other alternative and found some but it doesn't work just gives me a plain blank image when I pate the base64 on the image property with ""

Here's a blog that covers the basic steps.  It does require using Power Automate to do the conversion.

Ok, I did some playing around and found an easier way to do it without Power Automate.  You said upload, so this is using the upload media control.

1) Add a button to convert the Uploaded picture to Base64 using the JSON() function.  The JSON function will create a Base64 string surrounded by quotes.  You need to remove the quotes to use the image in an image control so I remove them at this point.

Set(myPic,Substitute(JSON(UploadedImage1.Image,JSONFormat.IncludeBinaryData),Char(34),""))

 2) Now you can Patch the text contents of myPic to a SharePoint text field.  In SharePoint it will show as text.  But if you load that text into an image control in Power Apps it will display the image.

No, the images were uploaded to sharepointlist using image column and displayed via gallery.

I tried using base 64 and its working but when I store the base64 string on list it doesnt fit since max is 255 characters only

[Pstork1]

Use multiple lines of text field instead and increase the number of lines to the size you need.  lines X 255 characters per line.  The max length for a multiline of text field is 1,048,576 characters.  If the image is bigger than that I wouldn't recommend storing it in SharePoint to begin with.  You can also increase the size of a single line of text field, but the max for that is 4,000 characters.  So even maxed its a bit small.
