How do I resize images to maximise site performance?
Should I do it before I load them to File Manager? If so, to what dimensions or file size?
And if I can do it inside Concrete5 - how?!
Thanks in advance
The c5 filemanager implements a thumbnail system that in the background prepares the images at various sizes.
These thumbnail sizes are a mix of default, declared by theme, and configured by you in the dashboard.
Blocks on the page use c5 classes to create image or picture elements and internally these use the best thumbnail(s) or create one specially for the use.
Sorry to be dim but could you give a rough guide as to what constitutes 'ridiculously big'?!!
c5 can cope with larger images, but resizing an image consumes server resources proportional to the dimensions of the image (not the file size, so compression doesn't help).
ie. resources required are proportional to image width x height
Servers often run out of resources and fail if an image upload involves a file straight off a digital camera or phone.
