Ok. Upped the upload max to 7M (was already set to 4M) in php.ini. No difference. Small files still ok. Large files no.
I changed the max width and height in the admin panel and they upload fine. But, the resized image that is shown (default is 600) looks very bad. So, the downres isn't working right. I'm assuming it is the same essential issue, GD2.
I gave up on GD2 and attempted to install ImageMagick per your instructions.
All goes well until I get to the line indicated below.
"$ cp makefile.linux ../makefile
In the line above, I used makefile.linux, but you should use your appropriate makefile. Continue:
$ cd ..
$ make <-------------All goes well until here.
$ make install
$ cd .."
It says "no targets specified and no makefile found. " The makefile.linux file is in the same directory. I checked and zlib is installed as the libpng install directions suggested this needed to be installed.
Where to go from here? This is starting to get really frustrating.
