I would like to know if you can tell me how to avoid uploading pictures less than 1600×700 (if the pic is less than that or its size is e.g. 300×3000 the listing picture will mess the whole thing) For what can I see, you post the property and then check the size of the picture. I have been testing and testing but the thing is that if the upload is after the posting, when I reject the picture because its size, it will post it no matter what (without the image)
Also, try to improve the img upload method, because if someone uploads a picture of 100Gb, despite WordPress will reject it, the upload will happend.
Thank you very much and keep working on this theme, we are about to finish our company thanks to you!
