I have uploaded images via ftp in my WordPress blog. I am using "Add from Server" plugin to attach images that is uploaded via ftp. The images are in the Upload folder. There are many subfolders inside that. Each folder name belongs to one article. The freelancer has to choose name of the article as that folder name and import all pictures of that folder to that particular post. Finally he/she has to save it as draft. That's it. Each post will have different number of the images. No search no writing is required.
Work involve only three steps
1) Writing post title (i.e. folder name)
2) Attach pictures from that folder to that post
3) Save it as draft and move on.
I have about 10000 folders and I will pay $10 for per 250 repetition of above three steps. No more no less. Freelancer having experience of the WordPress blog posting should only apply for this project. PM your experience. The time duration for the project is 2 days. Please don't bid if you don't have time at present as this project need only time and nothing else. I want to finish it in next 2-3 days.
