PDF not load photo

Posted on by blazejgorecki

Hello,
Uploads pictures to the sharepoint list as attachments. Everything saves correctly. Then I display all items from sharepoint list and all photos from attachments (as Gallery). Everything works on the screen. Then I create a PDF (using the PDF() function), and immediately upload it as an email attachment. My problem is that if I have pictures up to about 0.5MB they load correctly into PDF, if I have pictures bigger they don't load into PDF and PDF have errors. PDF file has 2 pages of content and then 100 empty. It should only have 2 pages.

Images are uploaded using a form (UploadedImage, AddMediaWithImage, attachCtrl)

Sharepoint list attachment collection code:

Collect(colAttachments;{DisplayName:"("&zm_ostatni_audyt&")"&GUID()&".jpg"; ID:"("&zm_ostatni_audyt&")"&GUID()&".jpg"; Id:"("&zm_ostatni_audyt&")"&GUID()&".jpg"; Value:UploadedImage3_1.Image});;
Reset(attachCtrl1_1)

Code to generate PDF and send email:

Office365Outlook.SendEmailV2(User().Email;"PDF"; "Body email";{Attachments:Table({Name:var_tmp &"_nr_"&number&".pdf";ContentBytes:PDF(Gallery4_1;{Size:A4;ExpandContainers:true})});

How to generate a PDF so that large photos load properly Or how to reduce the size of the photo before uploading to shapepoint list

Hi @blazejgorecki ,

I assume you are using HTML to create the PDF in Power Automate ? There is a "hard limit" of 2mb total size for any images here - no workaround as far as I know.

I am not using Power Automate to generate the PDF. I am using functions from PowerApps. Shouldn't the PDF generation be finished before the email send function is called. But I don't know how to make the variable containing the PDF an attachment to Emial.

Nice tutorial. However, in my case it doesn't solve the problem. This is definitely a problem with the generation of the PDF file by the PDF() function. By pdfviewer control I display generated variable with pdf file. Still my photos are not loading properly.

It's been awhile but I tried your solution. (No Flow). If I have the company logo a 25KB PNG on the screen of my Canvas App it does not show in the pdf and I get an error: Insufficient data for an image. I remove the logo from it and the PDF is generated as expected. I am beginning to think that there is a bug in the experimental add-on. Unless you can suggest something else. If you want, I can post it as an original question. Thanks

@TMAC27 ,

Yes it could be a bug and I have found issues with the proper display of images as well.

Still struggling with the PDF Viewer and image attachments:
I upload pictures to a SharePoint list as attachments.

✅ I’ve verified that everything is saved correctly.

✅ I also load the attachments into a collection to ensure there’s no issue with the image data.

✅ The images are displayed in a Gallery without any problem.

✅ Then I generate a PDF using the PDF() function and immediately send it as an email attachment.

The issue:

Some images randomly don’t appear in the generated PDF.

It’s inconsistent — the same image might appear in one PDF but be missing in another.

It doesn’t seem related to image size either — even larger images load fine.

Has anyone encountered this issue or found a workaround to ensure all images consistently render in the PDF?

Thanks in advance!
