On what basis shouldn't it, please? It's the first time
I've seen a BMP
file employed in this way. If this is likely to become a more common
procedure then surely NetSurf developers would wish to know, yes?
Like an Acorn Sprite, a BMP is an /uncompressed/ proprietary format so it
is bad form to use them in web pages or in html emails. BMPs do work
though, as every browser seems to be able to render them. Usually. Some
web counters, for example, do use the BMP format but those are usually
tiny files which arguably don't matter so much.
Perhaps in the hiatus caused by compuserve's proprietary stance about
GIFs, and before PNGs were widespread, some people in fear of being sued
for using GIF may have turned to BMP instead (they are most likely using
windoze, after all). Sometimes they would have been better than 'the
other choice': there is little worse than somebody using a heavily
compressed JPEG for a graphic. Such as this:
Blow that up and compare it to their graphic here:
It would seem that one web advertising company applies terrible lossy
compression to the ad you send them and makes your images look horrible.
TBH it often doesn't really matter if BMPs are used unless fools send
huge uncompressed photos in this way. You could be looking at a 30MB
instead of a 0.5MB download but generally its nothing to get worked up

If it was an HTML email then presumably the software simply embedded the
image the user threw at it. Hardly the program's fault, or do you expect
email software to process image file format translation to cope for
people who don't know the 'rules' better? ;-)

As could many Windoze Lusers. About everything. ;-D
Not my problem. It was commercial, thus drawing my attention to the
Would there be any point in telling a suit that he's sending out files in
formats he /perhaps/ shouldn't? Only if you can tell him he's losing
Unfortunately there is no easy way (under RISC OS) to reliably create
html attachments with embedded images which work in Pluto/NetSurf,
without wrapping them up in a zip file. Merely attaching a web page and
its images to a message doesn't work: the links in the HTML have to be
correctly written and this is done by windoze and other software if it's
used correctly. I suspect simple attachments were attempted by the sender.
Not NetSurf's fault. Sorry for long post.
