I guess, You'll also need some functionality for text-editing: image should be removed if one character of it is removed; this class can help (removes all the image text-placeholder if a char of it is removed)

public class ImageSpanTextWatcher implements TextWatcher {
    Object[] mTouchedSpans;
    int[] mSpanLength;
    boolean replacing = false;

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        if (s instanceof SpannableStringBuilder) {
            SpannableStringBuilder ssb = (SpannableStringBuilder) s;
            mTouchedSpans = ssb.getSpans(start, start + count, ImageSpan.class);
            if (mTouchedSpans != null && mTouchedSpans.length > 0) {
                mSpanLength = new int[mTouchedSpans.length];
                for (int i = 0; i < mTouchedSpans.length; i++) {
                    mSpanLength[i] = ssb.getSpanEnd(mTouchedSpans[i]) - ssb.getSpanStart(mTouchedSpans[i]);
                }
            }
        }
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        if (s instanceof SpannableStringBuilder) {
            SpannableStringBuilder ssb = (SpannableStringBuilder) s;

            if (replacing)
                return;
            replacing = true;
            if (mTouchedSpans != null && mTouchedSpans.length > 0)
                for (int i = 0; i < mTouchedSpans.length; i++) {
                    int newLen = ssb.getSpanEnd(mTouchedSpans[i]) - ssb.getSpanStart(mTouchedSpans[i]);
                    if (newLen < mSpanLength[i]) {
                        ssb.replace(ssb.getSpanStart(mTouchedSpans[i]), ssb.getSpanEnd(mTouchedSpans[i]), "");
                    }
                }
            mTouchedSpans = null;
            mSpanLength = null;
            replacing = false;
        }
    }

    @Override
    public void afterTextChanged(Editable s) {}
}
