Images won't display

I had successfully uploaded my logo, then I tried to upload an image to the page, it didn't work (file may have been too big), so I 'reset options' and when I tried to upload my logo again, it won't let me upload in any file format, but gives me this displayed instead of the logo." alt="successbyproperty.com.au" /> Can you pls advise why? Thanks.

 

Now the logo displays but none of my slider images do, once I press the save all changes button. I have made sure my images are the right size. They display before I hit save changes, but not after. Please help. PS. This support forum does not work in Google Chrome

 

Hello,

Please share the link of your website.

Thanks.

 

all sorted, sorry. If I upload the photos to the media file, then copy their URL, it works. But in the free version I did not have to do this. Thanks anyway.
