Tweaks default WordPress behaviour when IPTC caption of an uploaded image gets to description instead of caption field of the uploaded media form.
This plugin allows you to override the default WordPress behaviour by which the IPTC caption of an uploaded image is passed to the description field instead of the caption field of the uploaded media form. The Insert into Post button then uses the caption in the Caption shortcode like this:
[caption]<img (...) /> Caption[/caption]
This is not quite desired if you frequently upload plenty of images with IPTC caption written in Photomechanic, Lightroom, Photoshop or any other tool.
The plugin has only one setting option which lets you choose whether you want to copy or move the description to caption field.
