Hello Team,

I could not find anything in the code regarding a placeholder. My fix was to use absolute position to show another image on top of the fast image, and hide that view when the desired image finished loading. You can accomplish this by using the onLoad method.

In my case i was not showing a placeholder, but a progress bar, so I used the onProgress method.

For my case I'm using 1 placeholder for any image I load so I updated:
FastImageViewConverter.java

Drawable mDefaultSource = ResourcesCompat.getDrawable(res, R.drawable.nophoto1, null);
RequestOptions options = new RequestOptions()
            .diskCacheStrategy(diskCacheStrategy)
            .onlyRetrieveFromCache(onlyFromCache)
            .skipMemoryCache(skipMemoryCache)
            .priority(priority)
            .placeholder(mDefaultSource);

and FFFastImageView.m
- (void)downloadImage:(FFFastImageSource *) source options:(SDWebImageOptions) options { __weak typeof(self) weakSelf = self; // Always use a weak reference to self in blocks [self sd_setImageWithURL:_source.url placeholderImage:[UIImage imageNamed:@"noPhoto1.png"]

It would be a nice to have feature. Similar to defaultSource in normal Image component.

Any update on defaultSource props for library?
