How to Upload Large Images to WordPress Website
Does your site depend on uploading large size images? Do you want to sell high-resolution images through WordPress?
Uploading large size images in WordPress always end up with errors and that’s because WordPress adds a pixel-threshold on high-pixels images ( 2560px ). WordPress force scaling down any image bigger than that.
beside that, You will face a timeout error due to the long time request for uploading and resizing the image like that.
We made the WP Large Images Uploader plugin to solve these issues. The plugin uses a custom uploader to avoid the image max pixels threshold restrictions and also avoid the hosting timeout error.
The plugin tracks the upload and sub-sizes progress and also you can attach the image to any post after the upload
