Try this instead:
if [ "`find . -maxdepth 1 -name '*.jpg' -print`" != "" ]
# do what you want
The -maxdepth 1 restricts find to the current directory. Take it out
if you want to find anything in subdirectories. If you want to operate
on each file you want to write
for i in `find . -maxdepth 1 -name '*.jpg' -print`
# do something with $i
