the form submission takes quite long time when some images are attached to a post.
I don't think this is due to this plugin but maybe you have a trick.
Do you know why it can take quite some time?
Could it be the image processing in wordpress? I notice it generate 12 images sizes for each image submission.
3 defaults, 5 from the SELA theme, and I don't know where the 4 others are generated from.
Any advice is welcome.
