New to FTP

Hi, I'm new to this forum and smart FTP. I am trying to upload some images for a website. I'd like to upload a folder of these images. But, when I try to click/drag the image/folder or select them manually they don't show up in the queue. These are .bmp and .jpgs.
Is there a problem with images to transfer??
What am I doing wrong. I read some info on doing this, but I didn't find anything specific to images. I can connect to my server ok.

Hi, there is no diference from uploading images or other file types. Maybe you have added some file filters to disalow the upload of images, check at settings, filters.
