File upload error on mac browser not PC browser

Question

System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. at
System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams) at
System.Drawing.Image.Save(String filename, ImageFormat format) at
System.Drawing.Image.Save(String filename) at
Content.btnAddImage_Click(Object sender, EventArgs e) in
d:\inetpub\vhosts\rhinoreview.com\httpdocs\Content.ascx.cs:line 543

This process works perfect on any browser on a PC but does not work at all on any browser on a mac osx. A little lost on this one....

Answer 1

Nitpicking: it looks more like a download problem (from server to client) than an upload one (client sending a file to server).

Even more nitpicking: for me, PC means just Personal Computer. So computing running Mac OS or Linux or BSD or BeOS are just PC. I guess you mean PCs running Windows.

Wild guess, to add some value to this message: do you send the right headers along with the image?
It is hard to debug from the little info you provide (no code, no indication of language (C# likely) in the tags, etc.).

Answer 2

Wild guess, but it might be related to file extensions (it seems like GDI+ is failing when trying to convert the uploaded image to something it understands). I don't think Mac OS X needs them; are you uploading an image that doesn't have a file extension?

Answer 3

Is it possible to show us the code in the user control? Thanks.
