My site is running pretty slow also and when I add detailed images - I get this error:
Code:
Fatal error: Maximum execution time of 30 seconds exceeded in /home/equerrya/public_html/include/templater/plugins/function.thumb.php(2) : eval()'d code(1) : eval()'d code(1) : eval()'d code on line 35
My original image is large - 2014 x 1569 and 1mg in size
