since yesterday, I have been able to attach the following filetypes with no problem.
*.png *.gz and *.ipk
clicking on file links and attached pics still results in a page of code.
I use firefox 2.0.02 and this is how I have been downloading attachments lately.
attached pics, right click, save as. and guess if it's a jpg, png or bmp
attached files, I just copy the filename to the clipboard, then right click, save as, and paste filename into the save dialog.
