Computer Problem - Saving Photos in Bitmap vs jpg Format

[arara123]

Can any Dopers more computer-savvy than I help me out.

In the past, when I would save photos from the internet I would "right-click" on the photo and select "save picture as..." The name of the photo would appear and it would be saved as a jpg file.

For the past week or so when I have tried this I can only save the picture as a bitmap file and the name of the picture to be saved is always "untitled." If I try to change the "save as type" in the lower part of the box that opens I am not able to; "bitmap" is the only option available.

I called my help-desk and they couldn't tell me what was going on, except to say that they did'nt think there was anyway I could have changed the options to make this happen.

This happens on various websites so I don't think it's because the picture is stored as a jpg or bitmap on the original website.

Even stranger, sometimes (for a few minutes) the format will go back to jpg - and then beck to bitmap.

I would rather save all pictures as jpg files, they're smaller and I don't have to type a name to replace "untitled" every time.

Any help would be appreciated -- Thanks.
