A friend gave me an idea of building up an image board that has a main language in Spanish, so i did UTACHA (is like a beta image board i was using to test all image board scripts) i was testing it on 100webspace, but the beta test finished and we decided that the best script in speed of building the HTML and security was WAKABA.

So one of the users of the beta board, donatted to us a domain and web host, BUT it doesnt has ImageMagick installed for thumbnailing, and they arent very helpful =_=

And i dont want to enable the stupid_thumbnailig, because not only we will be affected in the overuse of Bandwith but those who are using 56k modems...

any help?, on what to do about thumbnailing?, changing of server is out of question...

I assume you tried running it, and it didn't have the NetPBM tools either? Wakaba will use those automatically if it can't find ImageMagick.

You could try finding a precompiled executable for convert from ImageMagick, and then uploading that to the host. Or finding a similar machine, compiling there, and uploading. Then, hack the CONVERT_COMMAND option to point to your own version. Getting this to work is tricky, though.

does Kareha need thumbnailer as well?

If you want to use it as an image board, yes.
