Delphi - Error when loading 96dpi jpeg file into Image.Picture

I can load a 72dpi jpeg file into TImage using
Image.Picture.LoadFromFile (FileName) ;
but not a 96dpi jpeg file.
If I change the code to the following, I get the same result
jpeg:= TJpegImage.Create;
jpeg.LoadFromFile(filename );
Image.Picture.Graphic := jpeg;
What changes do I need to make for 96 dpi images?
I use Delphi XE. Thanks

Sinisa Vuk

what error do you get?
Try "draw" method to convert jpeg to bitmap and then assign to image.

or attach the jpeg so we can do some troubleshooting

I have attached one of the offending jpeg files. An exception error, JPEG Error #53, occurs at
jpeg.LoadFromFile(filename );
Google search indicates #53 may be a memory issue - not much help really.

I can't see any attached file here.
Anyway #53 usually means that the jpeg file is corrupted. Have you downloaded it from internet? If so it could be not 100% downloaded, so there's not a correct file end that generates the out of memory error on reading it.
Someone tells that he solved this issue using TADVPicture from TMS Software (I don't have it installed, so I don't know if it's true).
Try reopening the file in Photoshop or some other Image tool and re-save it, Or if you have downloaded it just try downloading it again.

The file was emailed to me by a client (student photos from a school). I can load them into Excel so I don't believe they are corrupted. Once I submit this comment I will try attaching again. Having some trouble doing that - getting a request for file description?
