We have a tricky one and I was wondering if anybody could help me.
We've recently taken over the hosting of a Magento site for a customer. Their previous hosts were less than helpful and this has meant that the site is in a bit of state.
One of the major issues is that the site is using a large amount of bandwidth, around 30GB a month, due to the fact that all of the product images on the site are .png files.
I there an extension that will automatically resize and change the format of these images (to .jpgs)?
If not, if there a way to identify which product images are .pngs? I think they all are but it would be helpful to check.
If there's not an extension to do this automatically, I presume the only way to fix this is to create a new jpg image for each file and manually upload the updated images to each product?
Many thanks for your help
and with a combination of
gifsicle, ImageMagick, jpegtran, pngcrush
you can do with images whatever you want
