addImageToMediaGallery creates two image entries while having only one file

Question

What I've done:

• I've imported all my products once (without any problems regarding the images)
• Deleted all of them and then deleted all files under media/catalog/products
• imported all my products again
  • Now it creates two image entries in my product while only the first exists
    • 1234.jpg (only this file exists)
    • 1234_1.jpg (selected as default)

So i assume there is an cache, db entry, something which remembers the file which was there at some point.

Line which triggers the image import: $this->product->addImageToMediaGallery($this->filepath, array('image', 'small_image', 'thumbnail'), true, false);

Answer 1

Take a look at this answer - addImageToMediaGallery and getMediaGalleryImages
You might be saving the product multiple times, after each addImageToMediaGallery call. In this case, duplicate image paths (the ones with '_1' appended) will be created and added to the product, without the files actually being there. Moving product->save outside of any loop should help avoid this.
