I found a solution for ads with images being flagged by cl.
Here's solution:
1. Save your images in multiple formats like same images in jpg, gif, png, psd and so on.
2. After you save images in different formats upload to free image hosting sites such as
http://www.imagesne1.com where you can host up to 10,000 images for free with up to 15mb per image
3. Get image code from
http://www.imagesne1.com and starting pasting the image code to your ads.
Remember to change the image code to different image format everytime you post on cl because their server keeps cache and that's how they flag ads as spam or not.
Also, don't post more than 5 ads at a time on same ip or cl will flag it. To change the ip, simply go to your modem or router control panel (such as 192.168.0.1 or 192.168.1.1) and change one number in the mac address to get new ip so you can keep posting without ad being flagged.
To change the mac address just look for one box where it has number such as 14 and no letter. When you see that box, just change one number to anything you want such as 15 and then restart your modem or router to get new ip issued. Simple as that!
Have happy posting on cl!!!!!!!!!!!!!!!
