How to change size of image in post content but not via css?
Is there some way that script can generate more image sizes? It would be useful in case that user upload an image that is very big. So take this for example http://screencast.com/t/78z3zz8tVdoM . I changed this universe image size to fit into that div with css and it looks good. The actual image is very big, the size of it is 4.20mb. That is a lot if we consider that I don't need it to be displayed in full size. What can I do about this?
@Jelena If it's being uploaded locally, go to your ACP>Post settings, change Maximum File Size down to something more manageable. If it's being hosted externally on somewhere like imgur. You could edit the post after running the image through a site like compressor.io, then reuploading to imgur.
Alternatively, something like https://github.com/6px-io/6px-node to resize the image and resave it. Choice is yours.
@a_5mith tnx for replay smith. What we need is to have option for users to upload big images like 5mb, but we wanna display it in category listing as a smaller image, not whole 3000px image. So is there anyway we can get two images when users uploading it ? One with original size, and another which will be resized and showed under listing as many posts on same page.
And yes, it's being uploaded and hosted on our server.
