Hi! @eCom_Microware 

Can you please share me some of the details of CSV file if possible? I want to know below information.

1. Where your images are stored at the time of uploading?
2. What is the Images type? 

3. What is the file path you have selected?

Of course, follow your question answered

1. Where your images are stored at the time of uploading?
initially were in the folder "/var/www/html/pub/media/import" now in the folder "/var/www/html/var/import"
2. What is the Images type?
I have files "jpg" and "png"
3. What is the file path you have selected?
Already tried to put Magento root forward "var/import" and already put the full path "/var/www/html/var/import" and none of them worked
