lightweight linux distro for picture frame

I need a lightweight linux distribution for a picture frame. Its sole purpose in life will be to boot, and run the program feh to show a slideshow of the pictures on the flash drive or possibly from the internet.

Requirement: the program feh.

I would just use Ubuntu because that's what I'm familiar with, but I would have to buy a 4GB compact flash card even for Xubuntu because it requires 2.8GB. I would like to be able to install on a 1GB card, to save money.

I looked at DSL but by default it doesn't have apt-get, so I couldn't install feh. I'm a total linux noob, so I didn't know how else to install it.

knoppix is big though. The site says to have a 1GB or larger USB drive. My computer can't boot from USB so I have to use a 1GB CF card adapter.

I think DSL is easy to have use apt now that I googled it. I'll try it again I think. then I can hopefully just apt-get feh.

That won't work. I don't have an optical drive or internet access and my specs are very low <1GB hdd space, 128mb ram. I think DSL will work though; after some googling it seems it's pretty easy to enable apt. Then I can just install feh and live happily ever after.

Available where? The cheapest I found was the MicroCenter bulk CF cards, and they are $10 for 1GB and $15 for 2GB.

@DSL:

I have DSL installed and it's running pretty good, I just need feh. So then I ran into my next problem...the machine doesn't have an internet port. None. I think it had a docking station and the ethernet port was on that. So I can't even connect to the internet to try to download packages or enable apt. And DSL has the 2.4 kernal so I can't compile feh on this machine and copy it over either.

I think I'll grab my USB-to-CF adaptor from work tomorrow and try to boot into the CF card from a connected computer so I can download feh or enable apt. But really, this is turning out to me way more complicated that in should be. Maybe I should have sprung for a 4gb card, and just used xubuntu. But that seems like so much waste. Maybe I could just do a basic install, and add x? How big do you think that would be?

I didn't want to mailorder, though.

I gave up on DSL and installed a command-line Hardy system. I used a connected computer and a CF adaptor. I didn't do any stripping down after installing a command line system, then I basically just apt-get'd xorg and feh. Feh runs fine without a window manager.

The problems I have now are that I need it to auto-log me in, because I won't have a keyboard. I did a bit of searching but didn't find much.

I also need to place my 'startx' command somewhere, I'm not sure where.

And then, I need a permanent path for my 'start feh and play pictures' script, but I also need it to be on a flashdrive. So I think I might have to like add a 'mount flashdrive on boot' script in there somewhere or put it in the fstab or something. I'm not sure if I'll be able to remove and reinstall the flashdrive (with updated pictures) with the system up and running, but I would like to.

Apparently a commandline Hardy install and X fit on a 1GB flashdrive, but how can I check my free space? I'm used to like, using konqueror or system monitor or something.

What I ended up doing is a commandline Ubuntu install, with X but no window manager, which took only about 650Mb. Then I followed a internet guide on how to set up auto-login. Then I made a cron job that runs 'startx' every minute. Startx runs xinitrc, which runs Xsession, which is the actual X-starting-up-script. So in Xsession I bunged a script of my own that mounts the flashdrive to a directory in my home, and then runs feh in fullscreen mode, with a 20 second delay, and hiding the mouse pointer. There's currently no way to startx without running the slideshow, and running startx every minute is kinda kludged, but I guess it doesn't matter since it boots straight to the pictures now and has been running for a few days already.
