Access Controls Prevent Image Downloading
Occasionally merchants will prevent the downloading of their product images. In these cases, it is impossible to download the merchant images and upload them to your site.
To determine if merchants have image access controls in place, follow the 5 steps listed above. If you received "cURL" errors like cURL error 28: Operation timed out after 20001 milliseconds with 0 bytes received then that is an indication that access controls are in place.
In these cases, your only recourse is to " hotlink" the merchant's product images. Here's how:
Create a custom plugin
If you haven't done so already, create a custom plugin.
Add custom code
Add the following code to your custom plugin file.
Save the plugin and now any images that were being blocked from download should appear on your site.
