uploaded images don't display in webspace?

[#1]

Hi, I'm a new user without a lot of technical know-how. Apologies if this problem has been addressed elsewhere but I couldn't find it on a search.
Seeing we have 250Mb of webspace, I used filezilla to upload our (very basic) website. Everything is there except the images - it displays spaces instead. The files are small, jpgs and pngs, but are rather important as they are the charity's logos and banners showing our name and address.
Any suggestions?
Many thanks

Possibly a path issue?  What's the address of your website?
What happens if you try to access the image directly ie http://www.domainname.tld/images/image01.jpg

Think I've figured it out, just had a look at your website and can see the header image wasn't loading. It's pointing to image.jpg, if you change the file extension to image.JPG (capital letters) it works. I think mspaint defaults to saving as capitals, so something to keep an eye on.

Chris, thanks for that, I'll give it a try
