@joker_josue You need to set TalkImg.com as your avatar and signature! Seems crazy to not use those spaces and your reputation to promote TalkImg all around the forum.
I doubt it is needed as of now as TalkImg has grown organically through discussion and a lack of support from Imgur. At the moment TalkImg does not have any monetary support and if the owner wants to get some revenue through a signature campaign then I do not think that should be an issue. I do feel after a certain period of time TalkImg should introduce an advertisement revenue model. When it is done then that would be the right time to utilize the signature space for promoting TalkImg.
I guess TalkImg is already popular on this forum and there is no need for further promotion. However, the next step should be to make TalkImg for everyone (the Public) and not just for the bitcointalk users. Of course for that purpose, the sources would be required but the site can generate a lot of revenue once its starts to give other image-uploading sites competition.
